PROSPECTlNG-TOOL FOR MINERS, 80C.

SPECIFICATION forming part of Letters Patent No. 252,184, dated January 10, 1882.

Application filed June 18, 1881. (No motleL) To all whom it may concern:

Be it known that I, J. B. THORNTON CHASE, of Pueblo, in the county of Pueblo and State of Colorado, have invented a new and Improved. Prospecting- Tool for Miners, 850., of which the following is a full, clear, and exact description.

The object of my invention is to furnish a hand-tool especially adapted to the use of prospectors, geologists, miners, and coal-workers. The invention consists in acombined pick and hammer having certain novel features of construction Whereoyit is specially adapted to the required work, as hereinafter described and claimed.

In the accompanying drawings, Figure 1 is Figs. 2 and 3 are side views of the tool, and Fig. 4. shows the hook detached.

Similar letters of reference indicate corre-- sponding parts.

A is the tool fitted upon a handle, B. The tool is formed with a point or pick, a, heel or It is made of steel, and the point and heel are of equal weight of metal, or nearly so, so that the tool shall hang evenly in the hand and when placed in a belt for carrying. The point or pick portion a is long and tapers on all sides. The heel B may be of rectangular form in crosssection,'or with theangles chamfered,asshown, and is of suitable length for convenient use. The end is beveled in pyramidal form, so as to obtain a center point, cl, which is best adapted for rock-breakin g, as the full force of the blow comes at the point. The point a and hammer I) are curved in the arc of a circle the center of which is near the outer end of handle B, as illustrated by the dotted lines. The tool is thus the segment of a circle of which the operators hand will be the center, so that the best leverage can be obtained in prying.

The eye 0 is formed heavy and deepened by an extension, 6, at the inner side of the tool, so that it cannot break, and is otherwise most durable.

On the end of handle B is a ferrule, f, to prevent splitting and abrasion. A hook, 9, having a screw-shank is secured in the handle end, in which position it does not interfere with the use of the pick, and can be removed when desired; The hook is adapted for hooking over projecting branches and rock, or to catch in crevices in climbing. When the tool is used in that way the pick serves as a bar for being grasped by the hands.

The tool constructed in the form described is serviceable and convenient for prospecting and similar work. It is light and can be readily carried in a belt worn about the waist, so

as-not to interfere in Walking or climbing. At the same time it is large enough for the work.

For use as a gad. in Widening a crevice and loosening rock the point will be inserted in the crevice and driven with a sledge.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. A prospecting-tool having the curve of an arc of a circle and constructed with its pick portion tapering on all sides to a sharp point, and its heel made with a central projecting point, substantially as shown and described, and for the purpose set forth.

2. In prospecting-tools, the tool A, so curved that its longitudinal center shall form the arc of a circle having the pick a, tapering on all sides to a sharp point, and its hammer b, terminating in a pyramidal point, 61, in combination with handle B, having hook g removably secured in its outer end, substantially as shown and described, and for the purpose set forth.

3. Inprospecting-tools, the hammer end 1), formed with a pyramidal or pointed end, as and for the purpose set forth.

4. The combination, with a prospecting-tool and its handle, of the climbing-hook g, substantially as shown and for the purposes set forth.
